Corian sink overflow hose
 

The overflow drain valve on Corian BR sink has come loose. It appears to have been glued on.

Has anyone dealt with this? Lowe's etc. do not seem to carry the item. Not sure if it is a DIY project.

This overflow pipe is just glued on. If the pipe is still in good condition, I would remove all of the old adhesive and clean it up as well as possible. Then, I would reattach it with a generous amount of clear silicone adhesive. If that doesn't work, call a plumber.

We find these detached every so often. Because of that we always check them prior to filling up the sink. There are two ways we find this detached......sometimes just the hose is off the glued on nipple, so the hose could usually just be pushed back on....OR...the flange itself is off. This can be glued back on using silicone sealant.

For those who are not sure of you have this type, these are the sinks that are Corian and part of the Corian countertop. These are not the undercounter or overcounter type sinks.

In the photo, it looks like the adhesive on the nipple has deteriorated and come loose.

I had this exact problem with one of my Corian bathroom sinks. As already suggested, I cleaned off the old glue on the hose and the sink. Then I squeezed out a bead of silicone bathroom caulk and smoothed it around the hose. I slipped it back in the hole and jammed a soft sponge between the hose fitting and the post under the cabinet. Once the silicone dried, I removed the sponge. The hose has been leak proof for more than a year now. Good luck.

I will suggest using GOOP marine glue, this seems to be a little tougher than the typical silicone sealant. I have used this on several projects, including one that is outside in the birdcage for almost 6 years, and still in excellent condition. This product is available at ACE and the big box stores. Allow over night drying time.

Is this a thicker product that will fill gaps, like a caulk?

Yes, IF the gap is horizontal, if it is vertical, you will need to use tape or something similar to keep the Goop in place until it hardens as it flows much easier than typical silicone caulks.

Also, not sure if Goop can be painted as I have never tried to do that. It is clear, and i have used it for many different repair projects.

I have been a Corian fabricator for over 25 years. I have seen this a few times. If you can take some hot melt glue and fasten the overflow tube to the sink, use tape to hold it in place while gluing. Then reseal the tube to the sink with clear silicone.

If possible remove as much of the existing adhesive before sealing.
